What is a DI for?
By Al Keltz.
Direct boxes are often referred to as “DI” boxes.
This stands for “Direct Injection” as their main purpose is to convert unbalanced and/or high impedance instrument signals into a format suitable for direct connection to a mixing console’s mic input – without the use of a microphone..
What does 52 decibels sound like?
Every sound has a decibel level associated with it. If an item is 52 dB(A), then it has a sound similar in intensity to a electric fan, hair dryer, a running refrigerator and a quiet street. Other common sounds include a blender at 90 dB(A), diesel truck 100 dB(A) and a crying baby can reach 110 dB(A).
What EQ frequency is vocals?
Male vocals will tend to have their fundamental frequencies between 100–300 Hz, while the fundamental frequencies of a female vocal will usually fall between 200–400 Hz.
What does dB mean on a microphone?
decibeldB or decibel is a relative unit for the quantification of the audio level or audio level change. As it is based on a logarithmic scale, it more or less indicates levels as perceived by the human hearing. Each unit of the dB-scale represents a factor.
What is a master song?
A master recording is the official original recording of a song, sound or performance. Also referred to as “masters”, it is the source from which all the later copies are made.
What dB is safe?
Decibel Level Sounds at or below 70 dBA are generally considered safe. Any sound at or above 85 dBA is more likely to damage your hearing over time. Researchers have found that people who are exposed over long periods of time to noise levels at 85 dBA or higher are at a much greater risk for hearing loss.
How many decibels can kill a human?
Acoustic grenades can go roughly from 120 decibels to 190 decibels. German researcher Jurgen Altmann showed that a blast of 210 decibels or more affects the inner organs — the lungs — and could cause internal injury that could lead to death. A blast will impact the body, and would do so very violently.
What is HI Z?
As the letter Z is the commonly agreed upon abbreviation for impedance, then Hi-Z simply refers to “hi-impedance”. This refers to the input or output impedance of a device (in our cases an audio device). … A typical guitar, for example, generally needs to be connected to a Hi-Z input.
What does dB means in sound?
Decibels measure sound intensity Amplitude, reported on the decibel (dB) scale, measures its pressure or forcefulness. The more amplitude a sound has, the louder it is. The logarithmic decibel scale measures differently than a linear scale.
What does a compressor do music?
Compressors and limiters are used to reduce dynamic range — the span between the softest and loudest sounds. Using compression can make your tracks sound more polished by controlling maximum levels and maintaining higher average loudness.
What do mastering engineers use?
Equipment. Generally, mastering engineers use a combination of specialized audio-signal processors, low-distortion-high-bandwidth loudspeakers (and corresponding amplifiers with which to drive them), within a dedicated, acoustically-optimized playback environment.
What does 125 dB sound like?
100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine. 170 – 190 decibels: For example, a shot gun blast or a rocket lift off.
How many dB should a mastered song be?
You’re safe somewhere around -0,5 – -3 dB, depending on the quality of your limiters and such, but many experienced forumites think -3- -6 dB is better. It’s not the peaks and the limiter that are essential, though, it’s how you use compressors.
Should I normalize audio before mastering?
A: Few mastering engineers rely entirely on the normalization function of a software DAW to adjust levels. Normalizing increases the gain of an audio file until its loudest point (or sample) is at the maximum available level of the system.
Are microphones line level?
Wired and wireless microphones are typically connected to mic-level inputs, whereas most other audio devices use line level. (We’ll get to instrument- and speaker-level signals in a minute.)
What is a good reverb setting for vocals?
Move the pre-delay to about 30-40% or so as a starting point and see how it sounds. With your EQ, maybe set the high-pass around 200Hz and the low-pass at about 12kHz. In a situation like this, you may want to have more body in the reverb. The following example shows a dual-reverb setup.
What is normalize in logic?
Logic 8 and later offer a new Normalize check box in the Bounce dialog window. When it’s selected, Logic calculates the maximum possible volume for the bounce without exceeding 0 dBFS, and writes a resulting audio file with the optimum level for whatever format you are bouncing to.
What dB is mic level?
Microphone level is usually specified between -60 and -40 dBu. (dBu and dBV are decibel measurements relative to voltage.) Several different types of devices are used to boost microphone levels to line–level signals.
What happens when you normalize audio?
Audio normalization is the application of a constant amount of gain to an audio recording to bring the amplitude to a target level (the norm). Because the same amount of gain is applied across the entire recording, the signal-to-noise ratio and relative dynamics are unchanged.
Do I need a DI box for electric guitar?
It’s a good idea for gigging or recording guitarists. Even better for bassists and acoustic players. If you gig a lot or do a lot of studio recording, you should have a good DI box. It’s a good idea for electric guitarists; it’s an even better idea for bass guitarists and acoustic guitarists.
What is the 3dB rule?
3dB rule when measuring noise at work When you measure noise levels with a noise meter, you measure the intensity of noise in units called decibels, expressed as dB(A). … It is based on orders of magnitude, rather than a standard linear scale, so each mark on the decibel scale is the previous mark multiplied by a value.
Is Mastering necessary?
There is no doubt that adding mastering to your project will improve the quality of your music. Without it, your chance of making it in the highly competitive music industry decreases dramatically. For less than 40$, there is no argument: mastering is a necessity.
How loud should vocals be in a mix?
If you mix them too loudly, they will stick out. What dB should vocals be recorded at? You should record vocals at an average of -18dB for 24-bit resolution. The loudest parts of the recording should peak at -10dB and be lowest at -24dB.
What is 0 dB on a VU meter?
0 VU is equal to +4 dBu, or 1.228 volts RMS, a power of about 2.5 milliwatts when applied across a 600-ohm load. 0 VU is often referred to as “0 dB”.
What’s a preamp do?
A preamplifier (preamp or “pre”) is an electronic amplifier that converts a weak electrical signal into an output signal strong enough to be noise-tolerant and strong enough for further processing, or for sending to a power amplifier and a loudspeaker. Without this, the final signal would be noisy or distorted.
What dB should you audio level be at?
For safety, no peaks should be above -6db. Most video editors agree that the overall audio level of your audio mix (all of your audio combined) should normalized between -10db to -20db. I personally level my videos around -12db with occasional peaks to -8db. The trick here is to stay away from 0db as best you can.
How many decibels is too loud?
Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.
What should my master peak at?
A good rule of thumb is to keep steady signals such as rhythm guitars, synths or pads at somewhere between -20 and -16 dBFS, with transient peaks (such as occur from drums and percussive instruments) no higher than -6 dBFS.
How loud should you record guitars?
If you are recording direct, it’s important to make sure you have plenty of headroom when recording – a clean guitar can be very dynamic. Try to peak no higher than -10dB (learn more about gain staging here). There’s absolutely no need to record hot when working with digital audio.
How loud can a human yell?
Using everyday items you could probably measure sounds in the range of roughly 20 to 80 dB. … Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears!
What is the point of mastering a song?
How mastering impacts the sound of the record. One goal of mastering is to correct mix balance issues and enhance particular sonic characteristics, taking a good mix (usually in the form of a stereo file) and putting the final touches on it. This can involve adjusting levels and general “sweetening” of the mix.
